Simplify. Rationalize the denominator. 3/9-√2

Gwar [14]

$\frac{3}{9-\sqrt{2} } * \frac{9+\sqrt{2}}{9+\sqrt{2}}$

$\frac{27 + 3\sqrt{2} }{9^{2} - (\sqrt{2})^{2} }$

$\frac{27 + 3 \sqrt{2} }{81 - 2}$

$\frac{27 + 3\sqrt{2} }{79}$

Find the distance between M(-1,-10) and P(-12,-3) * Round to the nearest tenth.

DedPeter [7]

Answer:

13.0 units

Step-by-step explanation:

To find the distance between two points, we use the formula

d = sqrt( (y2-y1)^2+ (x2-x1)^2)

sqrt((-3--10)^2 + (-12--1)^2)

sqrt( (-3+10)^2 + (-12+1)^2)

sqrt( (7^2 + (-11)^2)

sqrt( 49+121)

sqrt( 170)

A frightened child is restrained by her mother as the child slides down a frictionless playground slide. If the force on the chi

MissTica

Answer:

Step-by-step explanation:

Given

Restrained Force $F=116 N$

Increase in Kinetic Energy $\Delta K.E.=30 J$

Distance moved d=1.9 m

Work done by all the forces is equal to change in Kinetic Energy of Object i.e. by gravity force, Normal force and Applied Force

$\Delta K.E.=W_g+W_f+W_N$

$30=W_g-F\cdot d$

$30=W_g-116\cdot 1.9$

$W_g=250.4 J$

(b)In absence of applied force thus

work done by gravity will be equal to change in kinetic Energy

change in Kinetic Energy $=210 J$
